Abstract:
... Filtration theory does not include the potential influence of pore structure on colloid removal by straining. Conversely, previous research on straining has not considered the possible influence of chemical interactions. Experimental and theoretical studies were therefore undertaken to explore the coupling of physical and chemical mechanisms of colloid straining under unfavorable attachment condit ...

Direct photolysis of PFOA by a 254-nm UV light (400 W) was found effective to decompose PFOA without presence of photocatalysts. Shorter-chain perfluorocarboxylic acids (PFCAs) and fluoride ions were formed during photodecomposition. Addition of TNTs as photocatalysts did not greatly e ...

Due to the refractory oxidation of brominated flame retardant, T-SRO was employed to remove Tetrabromobisphenol A (TBBPA) by the combination of first debromination and succeeding oxidation. It indicated that the T-SRO process resulted in a complete dec ...

In this study the photochemical behavior of atorvastatin (lipitor) was investigated at two different concentrations of 35.8 μM (20 mg L⁻¹) and 35.8 nM (20 μg L⁻¹) using a solar simulator and a UV reactor. Photochemical fate i ...

Abstract:
... Amoxicillin is a widely used antibiotic and has been detected in natural waters. Its environmental fate is in part determined by hydrolysis, and, direct and indirect photolysis. The hydrolysis rate in distilled water and water to which five different isolated of dissolved organic matter (DOM) was added, were evaluated. In the five different DOM solutions hydrolysis accounted for 5–18% loss of amox ...
